Description

Technical Field

[0001] The utility model relates to the technical field of furniture products, in particular to a folding reclining chair based on a linkage structure. Background Art

[0002] The folding recliner is designed according to ergonomics, is easy to fold, and can be used as a chair or bed. The existing folding recliner can adjust the legrests at 135-180 degrees. When the legrests are used at an angle of 180 degrees, the folding recliner is in a parallel state and can be used for lying; when the legrests are used at an angle of 135 degrees, it is in a chair configuration, but the legrests are tilted upwards. When the user uses the recliner in this configuration, it is inconvenient to sit directly on the chair surface because the legrest angle of 135 degrees is too large. The user needs to slowly sit on the chair surface first, and then put the feet on the footrests. It is necessary to slowly sit on the chair surface in multiple steps, resulting in a poor user experience. At the same time, the legs need to be placed along the legrests, and the activity space is limited. Some users feel uncomfortable in their legs.

[0003] For example, the Chinese utility model patent with authorization announcement number CN203619092U discloses a folding recliner, including a recliner body, armrests, and a support seat. The recliner body is composed of a backrest frame, a seat frame and attached chair legs that are movably connected. An adjustment plate is connected between the attached chair legs and the support seat. The support seat is connected to the armrests through an adjustment mechanism. A cloth cover is provided on the recliner body. The attached chair legs can be adjusted to different recliner configurations for sitting or lying down under the action of the adjustment mechanism. However, the attached chair legs are also tilted upward under the support of the adjustment mechanism, and the legrest angle cannot be achieved at 90°, that is, the legrest is perpendicular to the seat surface. When using it, it is still necessary to slowly sit on the chair surface in multiple steps, resulting in poor user experience and leg discomfort.

[0004] In our daily life, the folding recliner seats we see and use have various structural forms, but most of them adopt buckle or simple screw fixing structure, lack of labor-saving structure in the folding process, making it more laborious to use and less convenient. Summary of the invention

[0007] Furthermore, the support deployment member includes a first support leg and a second support leg, the first support leg is hingedly provided at the front ends of the left and right sides of the seat plate, the first limiting groove is provided at both ends of the lower surface of the backrest, the second limiting groove is provided at the rear ends of the left and right support plates of the seat plate, an L-shaped connecting block is hingedly provided between the first limiting groove and the second limiting groove, a third limiting groove is provided on the upper surface of the first support leg, a fourth limiting groove is provided on the upper surface of the second support leg, a sliding plate is hingedly provided in the third limiting groove and the fourth limiting groove, and the second support An arc-shaped limit groove is provided on the inner side of the leg, and the bending part of the L-shaped connecting block is embedded and limited in the arc-shaped limit groove. Armrests are provided on the upper surfaces of the first supporting leg and the second supporting leg, and the rear end of the armrest is hinged to the backrest. A support frame is provided on the lower surface of the armrest, and a plurality of limit blocks are equidistantly arranged in the support frame. A latch that cooperates with the limit block is spirally embedded on the sliding plate, and the latch is arranged between the limit blocks in pairs. A first reinforcing rod is provided at the lower end between the left and right first supporting legs, and a second reinforcing rod is provided at the lower end between the left and right second supporting legs.

[0008] Furthermore, buttons are provided on both left and right sides of the upper end of the backrest surface, a headrest is provided on the upper end of the backrest, a cloth belt is provided on the upper surface of the headrest, and button openings matching with the buttons are opened on both left and right ends of the cloth belt.

[0009] Furthermore, a groove is provided on the upper surface of the handrail at the left end, a folding plate is hingedly arranged in the groove, and a circular placement groove is provided on the upper surface of the folding plate.

[0010] Furthermore, a U-shaped seat is arranged on the front side of the first reinforcing rod, and a foot pedal is hingedly arranged between two vertical plates of the U-shaped seat.

[0011] The beneficial effects of the utility model are as follows: the utility model adds a supporting unfolding piece to the device, which can realize the overall folding and unfolding, and can realize the unfolding and folding of the recliner. It has a simple structure, is easy to process, and is easy to operate when in use. The overall thickness after folding is small, which is convenient for storage, thereby improving the user's experience and the comfort when sitting. Through the function of the foot pedal and the armrest, it can better facilitate the user to sit. The utility model can effectively save manpower and material resources and improve work efficiency.
